2. Description of the Related Art In passenger cars including so-called RV cars,
When manufacturing a four-door vehicle and a two-door vehicle with one vehicle type, it is common to use a common front door. At this time, the outer panel is integrally formed seamlessly around the door from the viewpoint of rust prevention and appearance for both the four-door car and the two-door car. And when sharing the thing of the four-door car and the thing of the two-door car, since the two-door car has no opening of the rear door,
The center pillar portion and the rear portion thereof are not required. Conventionally, when manufacturing a four-door car and a two-door car with one car type as described above, the front door is shared, but the side outer panel is prepared for each of the four-door car and the two-door car. Alternatively, as shown in FIG. 8, the D portion of the side panel 1 for a two-door vehicle, that is, the center pillar portion 2 is cut off, and the front frame portion 3 is used as a front side panel for a four-door vehicle. .

In the former case, since the side outer panel is a seamless unit, the die size is large and the investment cost is large. Therefore, it is difficult to adopt this method particularly when there is a great difference between the production amounts of the four-door vehicle and the two-door vehicle. In the latter case, the center pillar portion 2 is eliminated, and only the front frame portion 3 is provided. Thus, the carrier becomes unstable during carrying, and is likely to cause poor accuracy during assembly.

[0004] Japanese Utility Model Application Laid-Open No. 54-15916 discloses a front pillar, a side roof rail, a side sill,
The quarter panel, center pillar, etc. were assembled and welded together to form the side panel, but the inner surface of the center pillar on one side and the outer surface on the other side were split into two front and rear panels for accuracy improvement and vehicle deployment. Are formed and connected by a flange portion to form a box cross section. However, according to the technique shown here, for example, a side panel of a four-door car is divided into front and rear parts at the center pillar position so as to be inward and outward, and is formed into a box cross section by the center pillar. When the structure of the front part of the rear side panel is slightly different from the inside or outside of the center pillar, as occurs in many cases between a four-door car and a two-door car, for example. Not applicable to

[0005]

Therefore, the problem to be solved by the present invention is to make a small change to the side outer panel without making a large investment in the mold.
The side outer panel of the door car and the two-door car can be made common, and in this case, the accuracy is maintained, and the two-door car can be assembled even when the cross-sectional shape of the center pillar is different from the inside or outside. It is to provide a panel structure.
